Civil engineering and geodesy
Geodesy
Geodetic measurements determine the absolute three-dimensional movements of reference points on a dam or any other structure. In other words, they make it possible to evaluate and monitor...
Auscultation of civil engineering works
The auscultation of civil engineering works allows the owners of electricity generating facilities to assess the viability of their installations, as well as...
Multibeam and single beam bathymetry
Bathymetry enables topographic measurements to be taken of submerged areas of lakes, réservoirs and watercourses.
Dam monitoring
The objective of dam monitoring is to prevent long-term dam deterioration and to ensure dam safety. The Swiss concept for monitoring dams provides for 4 levels of monitoring.
Evacuation of accumulated sediment by pumping
With time, sediment accumulating in water storage points (dykes, dams, high altitude intakes, etc.) may obstruct water intakes, deep sluice gates and...
Management of sediment - Global Analysis
Solid material (SM) transported by water collected for the production of hydroelectricity has a negative impact on the exploitation of these facilities.
Management of sediment - Characterisation of Material in Suspension
The physical characteristics of transported Material in Suspension (M.E.S.) and its concentration govern the sedimentation mode of...

Marécottes: refurbishment of the reservoir gates
In 2020, SBB scheduled a lengthy shutdown in order to reconstruct the penstock at Corbes, which forms an integral part of SBB’s Châtelard-Vernayaz facility. SBB also took this opportunity to carry out other major works, naming the overall project “Barberine 2020”. Much of the work was entrusted to our company, one of the tasks being the refurbishment of the Marécottes reservoir.
Services: high voltage (HV) substation engineering works
Engineering work to refurbish HV substations is just one of the services we offer customers who have entrusted the operation of their facilities to us. Other customers who have used our services, include Swissgrid and Electricité d’Emosson SA.
